Language - The girl is wearing a school unifrom so as to tell the readers that she is a schoolgirl. Her smile indicates that she is enjoying her schooling. The scroll, rosette, desk and banners superimposed into the picture suggest that the girl has been very successful and won some kind of competition due to her being so smart. She's looking at the viewer, which makes them feel involved or like they are being singled out. Because it's a girl on the front, the magazine may be aimed mainly at girls. though the colour scheme does not suggest this. If the colours were more feminine we would believe that. The girl has a vibrant colour of hair, which tells us the magazine does not discriminate people with different hair.
Institution - The institution is unknown due to the fact that the name features no name other than 'Secondary Teachers'
Ideology - The fact that the girl is ginger tells us the institution does not discriminate against hair colour. The fact that the model has her tie pulled right up tells us that the institution believes in students dressing smartly and looking presentable. Her hair is down, but looks smart, which tells us that the institution has no problem with how students do their hair. The subheading 'Jamie Cullum: why music is a must' tells us the magazine has status because they can afford to interview a famous star for their magazine.
Audience - The audience is teachers, I assume, due to the fact that the name is Secondary Teachers. However, the picture looks quite childish and bright, something that would attract children, which makes me think it's maybe aimed at both teachers and students. The model is pretty, which appeals to girls because they'll see her like a role model if they think she looks nice.
Representation - Girls are represented by the female model, who is attractive so as to make females look good. People with red hair are represented by the pretty girl too.
